KM Application Switcher not working

I updated to KM 7.3.1 this morning and, ever since I did, my KM “Activate Application Switcher” macro stopped working. I had to disable it and revert to the system application switcher. The issue is that when I press the Command-Tab combination, it switches to the last application as though I had released the Command key, even though I keep holding it down, so all it does really is that it switches back and forth between the current and the last application. Any ideas as to why this might be happening?

I am running macOS Sierra 10.12 on a MacBook Pro.

I noticed that this was a problem happening to users of Logitech's wireless K750 keyboards. I didn't make the connection earlier since my keyboard was working perfectly fine before I upgraded to the latest version of KM this morning. I ended up deleting the Logitech Control Center (LCC) using the uninstaller and the keyboard is now working again.

This is the other thread where I found the temporary solution...
